| 基于生态产品总值（GEP）核算方法、地理探测器与地理加权回归模型，分析2023年安徽省104个县级行政单位GEP空间分异特征及驱动机制。结果表明：安徽省GEP呈现“南高北低”的阶梯式格局，高值集聚于皖南〖CD*2〗大别山生态屏障，皖北平原以物质供给为主导，皖南山区以调节服务与文化服务为核心；生态旅游收入与人口密度是社会因子中解释力最强的驱动因子，地形起伏度和森林覆盖率是核心自然因子，生态旅游收入与人口密度的交互作用对GEP的解释力达071；各主导因子对GEP的作用存在显著空间差异，森林覆盖率与生态旅游收入对GEP的正向效应由北向南递增，人口密度的负向效应由南向北递减，皖北平原土地垦殖率显著驱动物质供给，皖南山区生态旅游收入强力助推文化服务价值提升。 |

| Using gross ecosystem product（GEP） accounting methods， along with geodetector and geographically weighted regression（GWR） model， this study analyzed the spatial differentiation characteristics and driving mechanisms of GEP across 104 county level administrative units in Anhui for the year 2023. The results revealed a stepwise “high in the south and low in the north” pattern， with high GEP values clustered in the ecological barrier of southern Anhui and the Dabie Mountains. The northern Anhui plain was dominated by material provisioning services， whereas the southern Anhui mountainous area was centered on regulating and cultural services. Ecotourism income and population density were the most influential drivers among social factors， while terrain relief and forest coverage were the core natural factors. The interaction between ecotourism income and population density 〖GK!87mm〗exhibited an explanatory power of 071 for GEP. Significant spatial heterogeneity was observed in the effects of dominant factors on GEP. The positive effects of forest coverage and ecotourism income increased from north to south， while the negative effect of population density decreased from south to north. In the northern Anhui plain， land cultivation rate significantly promoted material provisioning， whereas in the southern Anhui mountainous area， ecotourism 〖HK〗income strongly enhanced cultural service value. |
